Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin? For example, less command is located under /usr/bin directory. Why not /bin, or /sbin, or /usr/sbin? What is the different between all these directories? In this article, let us review the Linux file-system structures and understand the meaning of individual high-level directories. 1. / – Root Every single file and directory starts from the root directory. Only root user has write privilege under this directory. Please note that /root is root user’s home directory, which is not same as /. 2. /bin – User Binaries Contains binary executables.

  We're platform agnostic at Lifehacker, which is why we love dual- and triple-booting our computers. Unfortunately sharing data between operating systems can be a huge headache. Here's how to stay organized by keeping it all in one place. There's nothing more annoying than booting into OS X only to realize you need access to some files on your un-readable Linux partition; or Windows; or any combination thereof. The more operating systems we put on one computer, the more our data can get scattered around different partitions that we can't read or write from other OSes. With the right drivers and a bit of organization, though, you can keep all your data in one central location, and read and write that data from any OS under the sun. Of course, not everyone triple-boots their system, so I've divided this guide into easily scannable sections, so you can skip right to the sections that apply to your machine (i.e., if you don't have OS X, you won...
